Storage and ISO Domain and Engine VM
This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --8DQ1estunpO0IIDrhSg9sVKrbFlJwL1AS Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi oVirt Team, I'm trying to set up oVirt 3.6 on three virtualization hosts connected to two other machines solely providing a replica 2 gluster storage. I know and understand that this setup is basically unwise and not supported but to prevent the gluster storage from going off line I followed the suggestion in https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3/html/Admi= nistration_Guide/sect-Managing_Split-brain.html 8.10.1.1 and added a dummy node with no bricks. Removing the requirement for replica 3 in nfs.py and allowing replica count 2 in vdsm.conf makes the installation possible without error. But at the first login on the web UI the only thing showing that's configured during the installation process is the virtualization host. The Engine VM is not listed in the Virtual Machines tab though the hosts shows one running VM. After watching several youtube videos from self hosed engine installations I'm guessing the Engine VM should be visible. Is there anything I can do? The Storage tab is completely empty. The ISO Domain that is configured during the install is not shown. As well as the gluster storage that is storing the Engine VM. I've heard in this video from Martin Sivak https://www.youtube.com/watch?v=3DEbRdUPVlxyQ that the storage domain where the Engine is stored is hidden. Why is that? So if the Engine storage is separated from the other VMs storage there should be two gluster volumes for VM storage if the self hosted setup is used? Why is the ISO Domain not shown? Since I'm (still) an oVirt newbie I'm guessing something has gone wrong during the installation or I'm missing some piece of the puzzle. So here are more details: - The gluster hosts are running an up date CentOS 7.1, Gluster 3.7. The volume where the Engine is stored has the recommended optimizations as described in http://www.ovirt.org/Features/GlusterFS_Storage_Domain - The self hosted engine deployment install is running on a minimal CentOS 7.1 (up to date). http://www.ovirt.org/Hosted_Engine_Howto#Fresh_Install - The repo from which oVirt is coming: http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm - I modified /usr/share/ovirt-hosted-engine-setup/plugins/ovirt-hosted-engine-setup/st= orage/nfs.py and substituted the replica 3 requirements appropriately for replica 2 - and added allowed_replica_counts =3D 1,2,3 in /etc/vdsm/vdsm.conf - hosted-engine --deploy runs without errors. Except for 'balloonInfo' errors vdsm.log doesn't show any (obvious) errors either. - The engine setup in the VM (CentOS 7.1 again) runs without problems as well. - After the install has finished the Engine is _not_ run automatically. After waiting some minutes I've started it running hosted-engine --vm-start. So far I've wiped everything clean and tried to install oVirt 3.6 twice and twice it was the same result so I'm not sure how to proceed. Any suggestions on what may have gone wrong or what I've missed to do?

That is true but we are still facing a issue there: https://bugzilla.redhat.com/1261996 We hope it will be solved for the next beta.
